Lubisol has created a new insulating material for glass furnace crowns

Lubisol Ltd. has
created a completely new and more efficient insulating material
(Lubisol 2-SLSuper Light) which has proved to be suitable to
partially replace the light silica brick insulation for glass furnace
crowns.

Lubisol 2-SL has,
as a main ingredient, foamed aluminium phosphate (AlPO4) in the form
of granules, applied by ramming. It does not react with silica when
heated up to 1640 oC. Lubisol 2-SL is about three times more
efficient in comparison with the light silica bricks. When the
Lubisol insulation package is applied on a glass furnace crown, the
heat losses are reduced by more than 800 W/sq.m. It has been applied
on more than 80 glass furnaces worldwide, a large part of them
belonging to leading glass producing companies.

The largest number
of crowns with Lubisol insulation is 18 float and container glass
furnaces, which is an excellent reference for the total success of
the Lubisol crown insulation.
